Submit оne single pdf file with the cоmpletes sоlution for the following problem. (10 pts) TRUE or Fаlse A product developer is interested in reducing the drying time of а primer pаint. Two formulations of the paint are tested; formulation 1 is the standard chemistry, and formulation 2 has a new drying ingredient that should reduce the drying time. Ten specimens are painted with formulation 1, and another ten specimens are painted with formulation 2; the specimens are painted in random order. The average drying times are 121 minutes for formulation 1 with a standard deviation of drying time of 8.1 minutes and 112 minutes for formulation 2 with a standard deviation of drying time of 7.9 minutes. The drying time is known to be normally distributed. What conclusions can the product developer draw about the effectiveness of the new ingredient, using α=0.05 A. (2 pts) Collect all numerical data, assigning correct symbols and notation. B. (2 pts) State the appropriate null and alternative hypotheses using correct symbols and notation. C. (2 pts) Calculate the test statistic. D. (2 pts) Find the p-value (range if appropriate). E. (2 pts) State the conclusion using correct mathematical terminology and the context of the situation.
